I am looking for the best way to advertise my books

I am the author of two books:  Surviving Being Single Past
40:  Living
Life Fully, With or Without a Partner and Surviving
Unemployment:
Staying Centered While Your World Turns Upside Down.
Any ideas on how to be (and cheaply) advertise them on the
web.
Contact me at survivingbooksaol.com

Thanks,
Valerie

subjects kinda too broad for ppc. if i were you i would go
the article
submission route. - write articles - have links to book in
your
signature.  google this method. - they have article blasters
that will
put in a bunch of ezines - it'll get indexed pretty quick

looks like people are going to have to like YOU and want to
read more
of what you have to say. convince them with subject similar
atricles.

Valerie,

You can create a campaign that targets content networks
only, which
will cause your ad to show on blogs and sites that discuss
topics that
Google thinks are close to the keywords in your campaign,
but will not
show your ad on Google search if you don't feel people are
explicitly
searching for the subject of your books.

You can also create site-targeted campaigns. If you know
specific
blogs, sites, or e-zines seem to appeal to the audience that
would be
interested in your books, and that display Google ads, you
may try
targeting these sites. This definitely requires some legwork
in
building a good list of candidate sites.

Good luck,
Dmitry
